Mirror paper? - or plastic mirror?

[Keith Outten]

I purchase 4 by 8 foot sheets of both silver and gold acrylic mirror from Norva Plastics in Norfolk Virginia. It looks just like glass mirror but it is lighter and can be cut with any type of saw or in my case a laser engraver. I expect that they will sell you cut sheets to your specifications.

If you're looking for small, check with Hobby Lobby or other craft stores. I'm sure I've seen 8x10 sheets of plastic mirror material at someplace like that.
